BAGGING ATTACHMENT FOR GRAIN-ELEVATORS.

SPECIFICATION forming part of Letters Patent No. 756,931, dated April 12, 1904.

Application filed January 5, 1903.

To all whom it may concern: I

Be it known that I, CHESTER BRADFORD, a citizen of the United States. residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Bagger Attachments for Grain-Elevators, of which the following is a specification.

The object of my present invention is to provide a suitable means for attaching the device known as a bagger to the discharging end of the clown-spout or discharging-conductor of grain elevators used as attachments to threshing-machines-such, for example, as that shown in Letters Patent of the United States No. 641,045, issued January 9, 1900, to the Pneumatic Elevator and Weigher Company upon the application of James B. Schuman; but as the elevator itself is not a part of my present invention it will not be further described herein, except incidentally in describing the invention.

Referring to the accompanying drawings, which are made a part hereof and on which similar reference characters indicate similar parts, Figure 1 is a side elevation of a pneumatic grain-elevator similar to that shown in Letters Patent No. 641,045, above referred to, provided with a bagger and the means of attaching the same such as contemplated by my invention; Fig. 2, a front elevation showing a fragment of the lower end of the discharging or conductor spout of the elevator, the bagger, the means of connecting said bagger to said spout, and the props by which the same are supported and steadied; Fig. 3, a

top or plan View showing a fragment of the lower end of the conductor-spout and the means of attaching the bagger thereto on an enlarged scale; Fig. 4, a view, partly in side elevation and partly in central vertical section, at the point indicated by the dotted line 4 4 in Fig. 3; Fig. 5, a transverse sectional view of the spout, showing the bagger attachment in perspective as seen from the dotted line 5 5 in Fig. 4; Fig. 6, a detail vertical sectional View through the bagger attachment at the point indicated by the dotted line 6 6 in Fig. 4, showing the lower end of the said discharging conductor-spout in perspective;

of a bolt 12, passing through cars 13, forming the adjacent ends of said band. Extending out from the band 11 are the arms 14, which are adapted to carry the pivot-rod 15, and upon this pivot-rod the head or hopper 16 is mounted. This hopper or head 16 is provided with a track-flange at the lower open end, upon which the bagger is mounted by means of suitable clips 17 and 18, which are secured to the upper portion 25 of said bagger, which (it may be here remarked) is composed of said upper part and the lower part 26, held together in any desired relation by the clamping-ring 27, which ring is provided with knobs or ears 28, which may, if desired, be utilized in staying or supporting the bagger by means of the props, hereinafter described, or otherwise. The clips17 are pref erably three in number and are riveted firmly to the upper bagger portion 25. The clip 18 is mounted in a housing 19, where it is adapted to be held by a cam-clamping lever 20. The bagger is thus adapted to be attached and removed at pleasure by simply manipulating the cam-lever and the removable clip, which when removed permits the others to be slipped sidewise off the track-flange onthe lower edge of the head or hopper 16. The head 16 itself may be of any suitable form for the purpose, it serving merely as a hopper to receive the grain from the discharging conductor-spout 10 and as a track or support for the bagger, whichis mounted thereon. It is shown as substantially a truncated cone, with one side out out suitably to admit the end of the elevator conductor-spout. I prefer this form for this particular style of machine, as it brings the parts into close relation, giving a compact and inexpensive construction. The weight of the bagger is supported at a central point by the pivot-rod 15, and is thereby well balanced. The track-like flange which receives the clips gives a turn-table construction, so that the bagger may be revolved to face in any direction. This is of advantage in always permitting the operative handling the sacks of grain to so position the bagger as to be able to stand on the windward side thereof in using it, and thus to as great an extent as possible avoid standing in the dust.

The grain in coming down the conductor.

spout 10 of course strikes against the opposite side of the head or hopper 16 and the portion of the bagger (or other suitable grain receiving and discharging device) which is at the timeimmediately therebelow. The-necessary loo'seness between the parts would, if no provision was madeto close it, leave a crack at this point through which some of the grain might escape. Ihavethereforeformed a small flange f at this pointat the lower edge of the head or hopper16, which extends down within the upper edge-:of the-upper portion 25 ofthe bagger, and thus covers and closes the crack in question and prevents any escapeof grain at this point.

Upon each sideof .the band 11 are'knobs or ears 21, which are :provided to receive the upperendvof the props by which the parts in question are supported and steadied. These props preferably consist of upper irons'22, adapted to engage With saidears, vwooden bars 23 of appropriate length, and pointed irons 24 on the lower ends of saidbars, :adaptedto enter the ground :or floor .sufiiciently to prevent slipping. These props or .similar ones ofa little shorter length may also be used :to support or steadythe bagger directlyby means of the knobsor ears28 thereon.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, in a grain elevator, of a pivotally-attached and downwardly-inclined discharging spout or conductor through which the grainlis discharged from said elevator, a hopper-support upon the lower end of said conductor, anainverted-hopper-like head pivotally secured tosaid support and having an open side intowhich the end of said conductor extends, and a grain receiving and discharging device .mounted by a swiveling jointat the lower edge of'said head.

2. The combinatiomina grain-elevatonof the discharging conductor -'spout thereof, a band adapted to besecured to the discharging end of said spout and provided witharms or bearings extending out therefrom, a hopper or head-piece pivotally carried from said arms or bearings, and a grain receiving and dis chargingldevice mounted on said hopper or head-piece.

3. Thecombination, in agrain-elevator, of the discharging conductor-spout thereof, a

band secured to the discharging end of said spout and provided with knobs or ears and also with arms or bearings, a hopper or headpiece carried from said arms or bearings, a grain receiving and discharging device carried on said hopper or head-piece, and props extending from said knobs or ears to the ground whereby said grain receiving and discharging device may be strongly and rigidly supported independently of the machine but without interfering with the manipulation of the grain receiving and discharging device itself.

4. The combination, in a grain-elevator, of the downwardly-inclined conductor, a grainreceiving hopper or head carried by said conductor, a grain receiving and discharging device swivelingly mounted upon said hopper or head, ears above said grain receiving and discharging device on a part attached to said conductor, and props the upper ends whereof are adapted to separably engage with said ears and which extend to the ground and constitute a rigid support for the grain receiving and discharging device independently of the machine from which the grain is received.

5. The combination, in a grain-elevator, of a conductor through which the grain is discharged therefrom, a pivoted terminal at the lower end of said conductor, a grain receiving and discharging device swivelingly. supported from said terminal, and props extending from the terminal structure to the ground and thus adapted to support and steady the grain receiving and discharging device whileleaving the latter free to swivel about its immediate support.

6. The combination, in a grain-elevator, of the discharging spout or conductor, a grain receiving and discharging device, and an intermediate hopper or head upon which said grain receiving and discharging device is mounted and into which said conductor discharges, said hopper or head being provided with a flange at the point opposite the mouth of the conductor which extends down within the upper edge of the grain receiving and discharging device, thus covering the crack at that point and preventing escape of any grain.

7. The combination, in agrainelevator, with the discharging spout or conductor, of a grain-receiving head or hopper supported by said conductor and provided with a trackflange at its lower edge, a grain receiving and discharging device carried from said grainreceiving head or hopper, clips attached to said grain receiving and discharging device forming the means of engagement to said track-flange, one of said clips (as '18) being removable, a housing (as 19) inwhich said removable clip is mounted, and acam-lever (as 20) mounted in said housing and adapted to impinge upon and hold said clip firmly in place'when in one position and to permit said clip to be removed and the grain receiving and discharging device thus removed when in the other position.

8. The combination, with a grain-elevator, of a grain-receiving head or hopper provided with a track-flange at its lower edge, a grain receiving and discharging device carried from said grain-receiving head or hopper, clips attached to said grain receiving and discharging device forming the means of engagement to said track-flange, one of said clips being removable, a housing in which said removable clip is mounted, and a cam-lever mounted in said housing and adapted to impinge upon CHESTER BRADFORD.
